There is very little difference between the different forest densities, in running speed, density and visibility. You may also want to replace the trees and textures with something more interesting. Furthermore the contour details are lost in height randomization. And please disable those violent trees.
Cambia el arbol asociado al circulo verde, que se vea bien :). Los limites de vegetacion no los esta interpretando bien. El verde oscuro quitale velocidad y que parezca mas espeso. Ponle el borde negro a los lagos impasables.
Espero que te ayude. Gracias por poner el mapa.
